Anomaloglossus Shrevei
''Anomaloglossus shrevei'' (common name: Shreve's rocket frog) is a species of frog in the family Aromobatidae. It is endemic to Venezuela where it is only known from the Cerro Marahuaca and Cerro Duida, two adjacent tepui A tepui , or tepuy (), is a member of a family of table-top mountains or mesas found in northern South America, especially in Venezuela, western Guyana, and northern Brazil. The word tepui means "house of the gods" in the native tongue of the ...s. Scientists have seen the frog between 350 and 1200 meters above sea level. These frogs live near streams in tropical rainforest. It is not a common species but the population may be presently stable and is protected by Parque Nacional Duida-Marahuaca. The IUCN classifies this frog as near threatened. Diseases may pose some threat. Climate change may threaten this species less than others because of its ability to live at low, medium, or high elevations. References shrevei Amphibians of Venezuela Endem ...

Juan A
''Juan'' is a given name, the Spanish language, Spanish and Manx language, Manx versions of ''John (given name), John''. The name is of Hebrew origin and has the meaning "God has been gracious." It is very common in Spain and in other Spanish-speaking countries around the world and in the Philippines, and also in the Isle of Man (pronounced differently). The name is becoming popular around the world and can be pronounced differently according that region. In Spanish language, Spanish, the diminutive form (equivalent to ''Johnny'') is , with feminine form (comparable to ''Jane'', ''Joan'', or ''Joanna'') , and feminine diminutive (equivalent to ''Janet'', ''Janey'', ''Joanie'', etc.). Chinese terms * ( or 娟, 隽) 'beautiful, graceful' is a common given name for Chinese women. * () The Chinese character :wiktionary:卷, 卷, which in Mandarin is almost homophonic with the characters for the female name, is a division of a traditional Chinese manuscript or book and can be tran ...

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Aromobatidae
The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs or cryptic poison frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are. Taxonomy The Aromobatidae were separated from the Dendrobatidae only in 2006, and some sources continue to treat these frogs as part of the Dendrobatidae. However, their position as the sister taxa is well supported, and the question is primarily about whether they should be ranked as a family or a subfamily. The validity of subfamilies within the Aromobatidae is also unsettled. Some evidence points to paraphyly of at least the subfamily Anomaloglossinae, and genus ''Allobates'', largely because of the uncertain placement of '' Allobates olfersioides''. Some species are reported to have a skunk like odor. This strong odor is secreted through the skin but theses frogs are not toxic. This strong odor is used a ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Venezuela
Venezuela, officially the Bolivarian Republic of Venezuela, is a country on the northern coast of South America, consisting of a continental landmass and many Federal Dependencies of Venezuela, islands and islets in the Caribbean Sea. It comprises an area of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. Venezuela is a presidential republic consisting of States of Venezuela, 23 states, the Venezuelan Capital District, Capital District and Federal Dependencies of Venezuela, federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the north and in the capital. The territory o ...

Cerro Marahuaca
Cerro Marahuaca, also spelled Marahuaka ( Ye'kuana: ), is a tepui in Amazonas state, Venezuela. It has an elevation of above sea level and is the second-highest mountain of the entire Guayana Shield (after the Cerro de la Neblina complex).Huber, O. (1995). Geographical and physical features. In: P.E. Berry, B.K. Holst & K. Yatskievych (eds.) '' Flora of the Venezuelan Guayana. Volume 1. Introduction.'' Missouri Botanical Garden Press, St. Louis. pp. 1–61. Cerro Marahuaca shares a common base with the much larger Cerro Duida and together they form the Duida–Marahuaca Massif.

Tepui
A tepui , or tepuy (), is a member of a family of table-top mountains or mesas found in northern South America, especially in Venezuela, western Guyana, and northern Brazil. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Notable tepuis include Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Anomaloglossus
''Anomaloglossus'' is a genus of frogs in the family Aromobatidae. The genus is endemic to the Guiana Shield in northern South America. It used to be placed in the family Dendrobatidae (together with other genera in the current Aromobatidae), and is still placed in that family by some sources. The name of the genus, from the Greek ''anomalos'' (=irregular, unusual) and ''glossa'' (=tongue), refers to the unusual tongue bearing the median Tongue, lingual process, the only unambiguous phenotypic synapomorphy of this genus. Description ''Anomaloglossus'' are characterized by cryptic dorsal coloration (brown or gray). Dorsal skin is posteriorly granular. The toes are webbed, ranging from basal to extensive. The fingers have weakly expanded discs. Many species show large intraspecific morphological variability and lack of morphological characters that would allow easy species identification. The tadpoles can be either exotrophic or endotrophic. Species The following 30 species are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Venezuela
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...
